Walt Smith Reef Rock

Walt Smith Reef Rock is manufactured by mixing reef substrate, that is a mixture of sand, coral pieces, shells and more, with a cement mixture allowing natural textures and shapes to be created. The reef substrate mixture allows the rock to have a porous network within the rock giving it many of the natural characteristics of rock straight out of the ocean.
After the rock is handmade it is then cured for 6 or more weeks allowing the cement and reef substrate mixture to fully harden and neutralize before it has a thick coating of purple, reef safe, paint applied around the entire exterior of each rock.
